Although the LICENSE file starts by saying it is GPL3, read further down
and you will find:
{{{
The CVXOPT distribution includes source code for a subset of the
SuiteSparse suite of sparse matrix algorithms, including:
- AMD Version 2.2. Copyright (c) 2007 by Timothy A. Davis, Patrick R.
Amestoy, and Iain S. Duff.
- CHOLMOD Version 1.7.1 Copyright (c) 2005-2009 by University of Florida,
Timothy A. Davis and W. Hager.
- COLAMD version 2.7. Copyright (c) 1998-2007 by Timothy A. Davis.
- UMFPACK Version 5.4.0. Copyright (c) 1994-2009 by Timothy A. Davis.
These packages are licensed under the terms of the GNU General Public
License, version 2 or higher (UMFPACK, the Supernodal module of CHOLMOD)
and the GNU Lesser General Public License, version 2.1 or higher
(the other CHOLMOD modules, AMD, COLAMD). For copyright and license
details, consult the README files in the source directories or the website
listed below.
}}}
So there are multiple licenses.
IIRC, it was me who added those comments, though it might have been
another package I'm thinking of.
